- 1. Claim. 1

. This invention comprises novel. and useful I improvements ina ventilatedmetal awning and more specifically pertains to a sheet metal awning of durableibutlight'. and economical construction which maybe readily mounted or dismantled for storage.

Theprimary object of this invention is to provide ametalawning for windows and the like whichshall be'of lightweight economical construction,peasily assembled on dismantled, which may be compactly stored; and which shall'be of a ventilated construction.

A further'object of". the invention is to provide a-metal awning in accordance: with the preceding object which is capable=of being assembled or-erectedin. a variety of; manners: and positions with respect to a window frame.

These, together .with various ancillary features and objects ofithe invention which-will later become apparent as the following description proceeds, are attained by thepresentzinvention, preferred; embodiments of; which have been illustrated by wayof example,- only in the accompanying drawings, wherein:

Figure -1, is a" perspective View, parts being broken away; of' one: embodiment of, the invention showing the sameassembled according to one-manner. of its-usage;

Figure 2-is;a sideelevationalview of the embodiment of Figure 1, whenshowingthe awning assembled in an alternativeposition or" manner of attachment;

Figure-.4. is a verticaltransverse sectional view taken substantially upon the plane of section line 4-4 of Figure 3. and illustrating the mounting-frame work of the awning;

Figure 5 is a perspective viewsimilar to Figure- 1 showing a second and simpler embodiment of the invention;

Figure 6 is a fragmentary vertical transverse sectional l view taken. substantially. on the plane indicated by the section line '6 6\ of Figure 5 and showing. in particularthe manner of mounting this embodiment of the invention upon a window frame; and

Figure 'l is avertical-longitudinal sectional view taken substantially upon the plane of section line-1'-'|'of'Figure 5.

Referring first to the preferred embodiment of the invention which is illustratedin Figures 1-4, it will be seen'thatnumeral l0 designates any suitable vertical supporting surface upon-which the awning may be mounted, such as for example as a window frame or the like, and to which this embodiment is intended. to be firmly secured in 2 either a rigidly fixed position as shown inFig-ure 1 or in a somewhat. elevated position as shown in Figure 2.

The awning itself'includes a pair of-sidepanels l2 formed preferably of. sheet metal such as aluminum or the like, and which are shaped in the-form of right triangles, which are disposed with their perpendicular edges forming respece tively inturned flanges M and [5 at their rear.

and lower edges, the other side. edge of the triangle being either a plain edge or seamed or. folded uponitself if desired. The awning f-urther'includesa roof panel preferably composed of a single sheet of. material although the same could be made up of a number of separate panels rigidly attached together in I knownmanner if desired, this roof panel being indicated by thenumeral l6, and being provided at its upper and bottom edges" with downwardlyturned integral flanges I8* and 20-, which respectively form. means for mounting or supporting the awning and. for providing a valance at the lower edge thereof; the roof panel being further provided with lateral downwardly turned flanges 22.

Itis intended that the triangular side panels may be detachably but rigidly secured to the.

roof panel It as by suitable rivets or the like 24; seeFigure 3, and alsoFigure 2, which. extend through the flanges 22 and the upper inclined edge of the triangular side panels: [2. Preferably the triangularmembers are disposed on the inner surface of the lateral flanges 22, so as to better prevent: the ingress of rain or the like to the interior or theawning to the joint formed by the side panels l2 and the lateral flanges 22-.

As will befurther apparent from Figure 3; the top down-turned. flange l8- of the roof panellfiis disposed between the upper portions of therear inturned flanges M of the side panels l2, so that the latter will assist in holding the roof panels against the. supporting surface.

The top downwardly turned flange l8 has at:- tached theretora hinge member 26; anew suitable; member of these hinges being provided whereby-the entire awning may be directly and.

hingedly connected to the vertical supporting surface I!) So that the awning may be raised or lowered as: desired. In its lowered movement, the awning assumes the position shown in Figure 1, and is rigidly retained in its lowered position by fasteningmeans which may conveniently, comprise I-bolts 2:8 secured to the. vertical surface l9 and extending through vertically elongated slots 30 formed in the rear flanges [4, whereby the. I-bolts may berotated. after their insertion in these slots to retain the awning in its lowered position.

The upper portions of the triangular panels 12, and of the lateral flanges '22, are perforate,

as by providing a plurality of apertures 32 extending therethrough, whereby heated air trapped beneath the upper inclined surface of the awning may readily escape thus cooling the space beneath the awning by permitting a circulation of air.

As shown more clearly in Figure l, the roof panel I 6 may be provided with appropriately positioned web-like ridges 34, which serve to reinforce and strengthen and add rigidity -to the thin sheet metal of which the awning is formed.

As so far described, it will be seen that the awning may be attached as shown in Figure 1 rigidly to a window frame or the like, and thus form a sharply sloping awning preventing the access of rain or snow to the upper part of the window, and shuttering the window space.

However, the assembly above described may also be alternatively positioned for a modified use. For this purpose, an extension member which may conveniently take the form of an L-shaped or angle iron member 36 is terminally pivoted as at 38 by a rivet or the like, to the lower inturned edge of the side panel I2 and at its other end is attachably secured as by a wing bolt 40 to the lower end of the lateral flange 22, whereby it may form a stiffening or reinforcing member as shown in full lines in Figure 3, when the awning is assembled in the manner shown in Figure 1.

However, the bolt 40 may be removed, the extension 3'6 may be pivoted about its pin 36, and the other end of the extension may be secured by the above mentioned wing bolt 40 to an I-bolt 42 appropriately positioned upon the surface I6, so that the entire awning assembly will be raised about its hinge 26 into the position shown in Figure 2. As will be seen, in this position the lowermost edge of the awning is raised higher, so that more light and air may be admitted to the window opening, while the window space is still protected by the awning roof from the direct effect of the suns rays, from rain, snow or the like.

Attention is next directed to Figures 5-7 which show a much simplified construction of awning which embodies some of the features of the invention, but which is intended to be detachably, rigidly but non-adjustably mounted upon a window opening. In this embodiment, the window opening I0 or other vertical supporting surface has rigidly attached thereto a pair of triangular side panels I !2 which may be identical with the side panels I2 of the preceding embodiment, including vertically andhorizontally disposed rear inwardly turned flanges H4 and upwardly turned flanges H6 at their lower ends, the upper edges of these side panels being secured as by bolts, rivets or the like H8, to the downwardly turned lateral flanges I20 integrally formed upon the roof panel I22.v This roof panel is provided with an integral downwardly turned bottom edge flange I24 together with a downwardly turned upper edge flange I26, the latter being mounted over the upper ends of the flanges H4 and between the flanges H4 and the vertical supporting surface 56. One or more reinforcing members in the form of angle iron members I28 are secured to the under surface of the roof panel ['22 as by rivets or bolts I30,

heated air from beneath the awning.

Also as in the preceding embodiment, the rear flanges I I4 may be provided with elongated key hole type of slots I 34 for detachably engaging fastening screws I36 carried by the vertical supand are terminally secured to the lateral flanges porting surface l0, these screws cooperating with clamping brackets I 38 suitably secured as at supporting surface I0 and adapted to overlap the flanges i I4 or I26 whereby the entire awning assembly may be detachably but rigidly secured-to the supporting surface I0.

From the foregoing, the construction and functioning of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and equivalents will readily occur to those skilled in the art after the consideration of the foregoing specification and accompanying drawings, it is not desired to limit the invention to the exact construction as shownand described. Accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claim. 1 v

Having described the invention, what is claimed as new is:

A sheet metal awning comprising a roof panel having lateral downwardly turned flanges and depending top and bottom end flange, triangular side panels having perpendicularly disposed inturned flanges on their rear and lower edges, said side panels being secured on their upper edges to the lateral flanges of the roof panel, said side panels and said lateral flanges being perforate at their uppermost portions to afford escape for heated air trapped beneath the awning, said top flange and said rear inturned flanges being secured to a vertical supporting surface, said side panels bearing an extension member terminally pivoted to the rear end of the lower inturned flanges and means for selectively securing the other end of the extension member to the front end of said lower inturned flange to form a reinforcing member or to said vertical supporting surface to hold the awning in an elevated position.
